Abstract

AIM:

To evaluate the results of treatment of erectile dysfunction (ED) in kidney transplant recipients before and after the advent of sildenafil.

MATERIALS AND METHODS:

From 1981 through 2002, 971 male patients of mean age 53.4 years received a renal graft. Erectile dysfunction (ED) was investigated in all patients at the first urologic visit posttransplantation. Psycho-sexual support was offered to all patients. Before sildenafil use (1998), our diagnostic approach was complex. From 1998 we tested: serum levels of testosterone, prolactin, and glucose with penile duplex ultrasonography and NPT reserved for selected cases.

RESULTS:

From 1981 through 1998, 365 male kidney transplant recipients (45%) reported ED. Only 169 patients chose to be treated: 27 responded to psycho-sexual therapy; 3 received testosterone with benefit; 133 had a good results from intracavernosal injection of vasoactive drugs; and 6 received a penile prosthesis. Since 1998, 126 patients reported ED (78.3%). Only 78 chose treatment: 24 patients had a satisfactory response to sildenafil (65% with 50 mg and 35% with 100 mg). PGE1 alone or in combination with papaverine and phentolamine produced a good response in 37 patients; 17 patients did not respond to pharmacotherapy; and 5 received a tricomponent penile prosthesis without complications. The side effects of sildenafil and PGE1 therapy were similar to those reported in the literature.

CONCLUSIONS:

ED is an important problem in male renal transplant recipients. Cultural resistance to treatment is common. However, treatment with sildenafil citrate and intracavernosal self-injection of PGE1 are well accepted, and prosthetic devices may help in resistant cases.
